I just got off of hCG drops. I believe they have something to do with garcinia cambogia.

Actually, hcg has absolutely nothing to do with garcinia cambogia.

Hcg, or human chorionic gonadotropin is a hormone produced in pregnancy by the chorion (part of which becomes the placenta). Hcg is called "the pregnancy hormone."

Hcg can be derived from the urine of pregnant women or the placenta after birth. As I understand it, urine is the more common source, but at least one Japanese pharmaceutical company uses human placenta. It has to come from a human source or it isn't hcg.

Garcinia cambogia is a citrus fruit (tamarind) extract. Tamarind is commonly used in eastern food and medicine. As a food ingredient, it adds a sweet and sour flavor to foods such as pad thai.

The concentration of garcinia cambogia in supplements are no higher than that found in a tamarind-based broth Indonesian women commonly eat to curb hunger before meals to lose weight.

It just dawned on me, that you are probably confusing hcg with HCA, the active component of garcinia cambogia, hydroxycitric acid, which is a derivative of citric acid (plain old orange juice type citric acid, only coming from a tamarind fruit not an orange).
